The Latest: Officials investigate how 4-year-old got gun

PALATKA, Fla. (AP) — The Latest on the Florida mother who was shot in the back by her 4-year-old son (all times local):

10:45 a.m.

A Florida woman whose 4-year-old son accidentally shot her in the back while they were traveling in her pickup truck is apparently a gun lover who made numerous social media postings about gun rights.

A Facebook page listed under Jamie Gilt for Gun Sense was filled with posts advocating for gun rights. It includes a quote that says “My right to protect my child with my gun trumps your fear of my gun.”

The Associated Press was unable to verify whether the page, which has since been taken down, belonged to Gilt. A person who answered the phone at her house on Thursday morning declined to comment.

Putnam County Sheriff’s spokesman Joseph Wells says 31-year-old Gilt owns the .45-caliber gun the boy fired from the back seat of the truck on Tuesday afternoon. Gilt was shot in the back and taken to a hospital, where she was in stable condition.

The boy wasn’t harmed and is with relatives.
